Narrative:

While working departure control at atlanta approach I received several aircraft from the tower spaced less than standard departure separation. I requested more spacing but did not receive the standard IFR separation required. Aircraft X flight and aircraft Y flight lost separation as soon as they departed atlanta airport. I turned aircraft X north to gain some separation. Atlanta approach controllers have been pressured to work with minimum, and sometimes less than minimum, separation between aircraft for years. This situation could have been prevented if the atlanta tower controller would have provided atlanta departure controller with the minimum 3 mi separation instead of 1.5 mi between these departing aircraft.

Title: A80 CTLR EXPERIENCED LOSS OF SEPARATION BECAUSE OF MINIMUM SEPARATION PROVIDED BY THE TWR.

Narrative: WHILE WORKING DEP CTL AT ATLANTA APCH I RECEIVED SEVERAL ACFT FROM THE TWR SPACED LESS THAN STANDARD DEP SEPARATION. I REQUESTED MORE SPACING BUT DID NOT RECEIVE THE STANDARD IFR SEPARATION REQUIRED. ACFT X FLT AND ACFT Y FLT LOST SEPARATION AS SOON AS THEY DEPARTED ATLANTA ARPT. I TURNED ACFT X N TO GAIN SOME SEPARATION. ATLANTA APCH CTLRS HAVE BEEN PRESSURED TO WORK WITH MINIMUM, AND SOMETIMES LESS THAN MINIMUM, SEPARATION BTWN ACFT FOR YEARS. THIS SIT COULD HAVE BEEN PREVENTED IF THE ATLANTA TWR CTLR WOULD HAVE PROVIDED ATLANTA DEP CTLR WITH THE MINIMUM 3 MI SEPARATION INSTEAD OF 1.5 MI BTWN THESE DEPARTING ACFT.
